Question

the flowchart below shows the three generations of a cross between a pea plant that has yellow pods and a pea plant that has green pods. green pods are the dominant trait. the flowchart is missing the labels that describe the traits.
flowchart with a (blue), b (white), c (blue), d (blue), e (white)
in which squares should the phrase \green pods\ appear?
○ a and d only
○ b and e only
○ a, c, and d only
○ a, b, c, d, and e

Explanation:

1. Green is dominant (let's say allele \( G \)), yellow is recessive (\( g \)). One parent (A) has green pods (could be \( GG \) or \( Gg \)), the other (B) has yellow pods (\( gg \)).
2. The first - generation (C) from crossing a green - podded and yellow - podded plant: If A is \( GG \), all C are \( Gg \) (green); if A is \( Gg \), C will be \( Gg \) (green) and \( gg \) (yellow), but since green is dominant, the dominant trait (green) should be in A (green parent), C (F1, mostly green as dominant), and D (F2, green as dominant trait will be more common). E is yellow (recessive). So A, C, D should have "Green pods".

Answer:

A, C, and D only
